Description

Устройства дл  регулировани  давлени  отбора нара дл  регенеративного подогрева воды на паровозе в фазе расширени  или предварени  выпуска известны,Devices for regulating the pressure of the bleed for regenerative heating of water on a locomotive in the expansion or pre-release phase are known,

В предлагаемом устройстве дл  изменени  давлени  сжатого воздуха в цилиндре сервомотора отборного клапана применена система дроссельных клапанов, трубопроводы которых приключены к переключателю подачи воздуха. Каждый клапан соответствует определенной отсечке.In the proposed device, a system of throttle valves is used for changing the pressure of compressed air in the cylinder of the servomotor of the sampling valve, whose piping is connected to the air supply switch. Each valve corresponds to a specific cut-off.

На чертеже изображена схема предлагаемого устройства. В схеме прин т случай, когда отбор пара производитс  от цилиндра паровой машины во врем  расширени .The drawing shows a diagram of the proposed device. The scheme assumes the case when steam is taken from the cylinder of the steam engine during expansion.

При данной отсечке клапан 2 прижимаетс  к своему гнезду давлением пара в цилиндре 7 до тех пор, пока давление во врем  расширени  не упадет до величины давлени  пара в начале отбора.With this cut-off, the valve 2 is pressed against its nest by the vapor pressure in the cylinder 7 until the pressure during expansion reaches the vapor pressure at the beginning of the extraction.

В этот момент в результате давле .ни  воздуха на уравнительный поршень 3 клапан 2 открываетс  и сообщает паровой цилиндр с внутренней частью клапана 4. При оптимальных услови х отбора .пара давление воздуха на уравнительные поршни 3 и 5 равно соответствующим давлени м в цилиндрах (5 и 7. Таким образом при падении давлени  пара в цилиндре 7 до величины конечного давлени  отбора в результате давлени  воздуха на уравнительный поршень 5 закрываетс  клапан 4 и прекращаетс  выпуск пара в теплообменник. Отбираемый от машины пар проходит через маслоотделитель 8 и поступает в теплообменный аппарат 9.At this moment, as a result of the pressure of the air on the balancing piston 3, the valve 2 opens and communicates the steam cylinder with the inside of the valve 4. Under optimal selection conditions, the air pressure on the balancing pistons 3 and 5 is equal to the corresponding pressure in the cylinders (5 and 7. Thus, when the vapor pressure in the cylinder 7 drops to the final extraction pressure as a result of air pressure on the balancing piston 5, the valve 4 closes and the steam release to the heat exchanger stops. The steam taken from the machine passes through the oil separator 8 and enters the heat exchanger 9.

В теплообл енном аппарате 9 пар конденсируетс  и через лабиринтовый конденсационный горшок 70 направл етс  в водоструйный эжектор 77. Далее смесь конденсата с тендерной водой подаетс  к вод ному цилиндру поршневого питательного насоса 72.In a heat exchanger 9, steam is condensed and directed through a labyrinth condensation pot 70 to a water jet ejector 77. Next, the condensate mixture with the tender water is supplied to the water cylinder of the piston feed pump 72.

Из питательного насоса вода поступает по нагнетательному трубопроводу ТЗ через переключательный кран 74 в теплообменный аппарат 9. В теплообменнике вода подогреваетс  и через питательный клапан 75 поступает в котел.From the feed pump, water flows through the discharge line of the TZ through the switching valve 74 to the heat exchanger 9. In the heat exchanger, the water is heated and through the feed valve 75 enters the boiler.

Дл  обеспечени  оптимальных условий отбора пара во врем  расширени  при данной отсечке необхо103To ensure optimal steam extraction conditions during expansion, this cut-off is necessary

димо соответствующим образом измен ть давление воздуха на уравнительные поршни J и 5. Дл  этой цели предусмотрен переключатель подачи воздуха 7(5.Air pressure can be adjusted accordingly to equalizing pistons J and 5. For this purpose, an air supply switch 7 (5.

При указанном на схеме положении ручки крана 77 внутренн   часть переключател  16 сообщаетс  с воздухозаборной колонкой посредством трубопровода 18, регул тора давлени  19 и трубопровода 20.With the position of the knob of the crane 77 indicated in the diagram, the inner part of the switch 16 communicates with the air intake column via conduit 18, pressure regulator 19 and conduit 20.

Часть воздуха из переключател  16 поступает через штуцер 27 и трубопровод 22 в цилиндр 6, а друга  часть - через клапан 23 и трубопровод 24 в цилиндр 7. Из цилиндров б и 7 по трубопроводам 25 и 26 воздух направл етс  в пространство над уравнительными поршн ми 3 и 3, обеспечива  соответствующее давление пара в начале и в конце отбора. Дл  получени  необходил ых давлений воздуха в трубопроводах 22 И 24 имеютс  дроссельные клапаны 27, 28, 29, 30, 31 и 32, приключенные к переключателю подачи воздуха 76 трубопроводами 33, 34, 35, 36, 37, 38.Part of the air from the switch 16 enters through the nozzle 27 and the pipe 22 into the cylinder 6, and the other part through the valve 23 and the pipe 24 into the cylinder 7. From the cylinders b and 7 through the pipes 25 and 26 the air is directed into the space above the balancing pistons 3 and 3, providing the appropriate vapor pressure at the beginning and at the end of the extraction. To obtain the required air pressures in pipelines 22 and 24, there are throttle valves 27, 28, 29, 30, 31 and 32, which are adapted to the air supply switch 76 by pipelines 33, 34, 35, 36, 37, 38.

Клапаны отрегулированы так, что при соответствующем положении ручки 77 переключател  76 в трубопроводах 22 и 24 обеспечиваютс  необходимые давлени .The valves are adjusted so that with the appropriate position of the knob 77 of the switch 76 in the pipelines 22 and 24 the necessary pressures are provided.
